Abstract: A low medicament sensor for a medicament delivery device having a reservoir, a pump, and a fluid path therebetween for medicament, the sensor including a switch and a snap dome. The snap dome is initially in contact with the switch, in fluid communication with the fluid path, and configured to snap out of contact with the switch when a pressure within the snap dome decreases below a predetermined pressure.

Abstract: A handheld electronic device, such as a smartphone, and an app capture an image of a medication or delivery device at the time of delivery with a date and time indictor or stamp. The image is analyzed and the dosage calculated from the captured image. The device stores the data corresponding to the dosage and time and compares the data with stored information relating to the patient to record compliance with the prescribed medication and delivery protocol. The data is used to record total usage of the medication over a predetermined period of time and determine a time schedule for resupplying the medication and a delivery method when the total medication usage exceeds a predetermined amount.

Abstract: A pump suitable for use in a wearable medical device, such as a patch pump, comprises an axially translatable chamber with an inlet and an outlet, a piston or a diaphragm rotatably received in the chamber, a first valve between the inlet and the chamber, a second valve between the outlet and the chamber, a cam affixed to the chamber, a follower affixed to the piston and in contact with the cam for axially translating the chamber, and a biasing means acting on the chamber for applying a force on the chamber in an axial direction of the chamber to maintain such contact.

Abstract: A medicament delivery device comprising a housing connected to a base and enclosing an interior, the interior having a fluid channel wherein the fluid channel passes from a first position in the interior, to a second position outside the interior, and to a third position in the interior.

Abstract: A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The rotary pump includes a plunger and optional stopper formed from a two-shot molding process, and including seals overmolded onto the head of the plunger and the head of the optional stopper.

Abstract: A device for delivering medicament into skin of a patient, the device having a housing, which includes a reservoir for housing the medicament, a first internal region that is sealed from fluid ingress and includes one or more components, and a second internal region that is not sealed from fluid ingress and includes one or more components. The housing also has a barrier that separates the first internal region and the second internal region, a delivery cannula that delivers the medicament into the skin of the patient, and a base including a bottom surface for orienting toward the skin of the patient. The bottom surface of the base has one or more fluid channels disposed therein and at least one of the fluid channels is in fluid communication with the delivery cannula.

Abstract: A medical device with a volume sensor is provided for administering liquid drug therapy to a user. The medical device comprises a flexible reservoir for housing a supply of a liquid drug, a rigid structure with a chamber and a side hole in fluid communication with the flexible reservoir, a plunger mounted inside the chamber and configured to seal one side of the chamber, and a switch implemented to indicate the position of the plunger. When the inside end of the plunger passes the side hole, the switch is activated to transmit a signal indicating liquid volume in the flexible reservoir.

Abstract: An administration system for delivery of a pharmaceutical composition to a patient has a delivery device configured to deliver a dose of the pharmaceutical composition to the patient and a notification device in communication with the delivery device. The notification device is configured to communicate information about a status of at least one property of the delivery device. The delivery device is a wearable automatic injector configured to be worn on the patient's skin. A delivery device of the present disclosure allows a user or patient to view the status of a container. For example, a delivery device of the present disclosure provides a simple and effective visual means of displaying fill confirmation and delivery confirmation.

Abstract: A filling member (43) in a medicament delivery device (1), the filling member (43) includes a first conduit (12) that fluidly communicates with a reservoir (4) and a second conduit (14) that fluidly communicates with a pump (3) and with the first conduit (12), wherein the filling member (43) provides two-way medicament flow that enters the reservoir (4) via the first conduit (12), exits the reservoir (4) into the first conduit (12) and the second conduit (14), and exits the second conduit (14) to the pump (3). The reservoir (4) includes a reservoir tube (44A) having one end that is formed with the reservoir (4), and the reservoir tube (44A) having another end that is press fit to the filling member (43) to establish fluid communication with the reservoir (4).

Abstract: An insulin infusion system is provided with a manual insertion device having a dual retraction spring (230) configuration for automatic introducer needle (222) retraction. A button (200) of the insertion device is used to insert the introducer needle (222) and catheter (202), and once the introducer needle (222) and catheter (202) have been fully inserted, a rotating engagement releases the dual retraction springs (230) such that the introducer needle (222) automatically retracts, leaving the catheter (202) in the body of the user. An end of the introducer needle (222) remains in the inserted catheter (202) and/or in the septum (206) of the inserted catheter (202) to provide an uninterrupted fluid path.
